- Radiographs are used extensively by dentists to look for damage or decay to teeth.
- Radiographs where taken with film which was placed directly into the mouth and then exposed with a beam emitter from an X-ray gun.

Therefore many dentists have gone to using digital radiographs where the images are available immediately after being taken and the images are usually displayed larger than actual-size to better read the detail of the image. This is fine for diagnosing caries, but when these images are taken in preparation for the placement of a dental implant or root canal treatment the dentist can no longer tell from the radiograph the length of the tooth or the amount of bone present.

This process comprises the steps of providing a dental X-ray reference device comprised of a radiopaque marker having a known dimension and a tooth overlay molding adapted to secure the radiopaque marker in close proximity of a tooth, or alveolar ridge. The dental X-ray reference device is then positioned in a mouth of a patient. The radiopaque marker is positioned over the edentulous area or over a tooth. Then an X-ray sensor is positioned behind the tooth, or alveolar ridge, and behind the X-ray reference device. A radiograph of the tooth or alveolar ridge, and the radiopaque marker is taken.
Description
- The present invention provides a radiography reference tool, which provides a known reference for use with digital X-ray equipment to facilitate dental work such as root canal treatment and the placement of dental implants.
- Radiographs are used extensively by dentists to look for damage or decay to teeth. Traditionally radiographs where taken with film which was placed directly into the mouth and then exposed with a beam emitter from an X-ray gun. This would take an image which is roughly the same size as the tooth, but it would require that the film be processed so that it can be read which takes time. Therefore many dentists have gone to using digital radiographs where the images are available immediately after being taken and the images are usually displayed larger than actual-size to better read the detail of the image. This is fine for diagnosing caries, but when these images are taken in preparation for the placement of a dental implant or root canal treatment the dentist can no longer tell from the radiograph the length of the tooth or the amount of bone present. Therefore if implants are necessary the sizes needed are hard to determine from a digital radiograph.
- One solution to this problem is to have a custom reference device made up and put this in the mouth along with the X-ray sensor in order to have a reference point projected onto the image for measurement purposes. The problem here is that these devices are costly.
- Therefore there is a need for an X-ray reference device that is inexpensive that can still accurately provide a reference marker of a known size which can be used with this equipment to either calibrate the area of anatomy on the image or serve as a reference point so that the dentist can use this reference marker to calculate the length of the root of a tooth or calculate the amount of bone present.
- A dental X-ray reference device comprised of a radiopaque marker having a known dimension and a tooth overlay molding adapted to secure the radiopaque marker in close proximity to a tooth. Also disclosed is a process for measuring teeth for dental implant placement or measuring the length of teeth for purposes of root canal treatment. This process comprises the steps of providing a dental X-ray reference device comprised of a radiopaque marker having a known dimension and a tooth overlay molding adapted to secure the radiopaque marker in close proximity of a tooth. The dental X-ray reference device is then positioned in a mouth of a patient. This device may be used on edentulous patients.

X-ray reference device 30,FIG. 1 , is a measuring tool that allows the dentist to accurately measure the length of teeth for root canal treatments and measure the amount of bone height present for implant placement. ThisX-ray reference device 30 comes in several sizes for the anterior and posterior arch segments. TheX-ray reference device 30, can be either a plastic, rubber, or cardboard instrument. TheX-ray reference device 30, may containing oneradiopaque marker 12,FIG. 8 , ormultiple radiopaque markers FIG. 6 . Theradiopaque marker 10 is a reference object of a known size which is capable of leaving an image, areference shadow 90,FIG. 4 , onperiapical radiographs 80 or panoramic images, 100,FIG. 9 . Theradiopaque marker 10 may be spherical or another geometric shape of a known size. When theX-ray reference device 30 is placed on a facial surface of atooth 40,FIG. 2 , it provides areference shadow 90,FIG. 4 , in takingperiapical radiographs 80 orpanoramic images 100,FIG. 9 . Thisreference shadow 90 allows the dentist to make precise measurements of the tooth or surrounding bone. TheX-ray reference device 30 may be sterilized and used on more than one patient (provided that it is sterilized between uses and provided that it is not labeled as a single use device.) TheX-ray reference device 30 may be customized with acrylic resin or impression material as a single use/patient specific device. - The X-Ray
reference device 30,FIG. 1 , is comprised aradiopaque marker 10, which can be a precision milled ball bearing having a known diameter (e.g. 5mm) that is mounted in atooth overlay molding 20. In operation thisX-Ray reference device 30,FIG. 2 , is placed over atooth 40 so that theradiopaque marker 10 is positioned over a facial surface of the tooth and theX-ray receptor 50 is placed in the patient'smouth 70. The X-rays emanate from theX-ray gun 60 and are recorded on thereceptor 50. Thereceptor 50 can be a digital receptor or it can be a receptor for a film image. When using a digital receptor theimage 80,FIG. 4 , is sent back to a computer. This computer may have a larger monitor and theX-ray image 80 would usually be blown up to show detail. However, the dentist loses the scale of theX-ray image 80. Then the dentist would have to try and make measurements of the patients tooth and mouth, which can be time consuming. - With this
X-ray reference device 30,FIG. 2 , a geometric shape of a known size, such as a precision ball bearing can be used as theradiopaque marker 10 to provide areference shadow 90,FIG. 4 , which can be used to gauge the size of thetooth 40, which aides in the oral surgery procedure or dental procedure. Many of the digital X-ray systems come with a program that provides a dentist with a way to make measurements if there is a known reference point. When taking an image of the patient's mouth alone, there are no known reference points so that this software really cannot be used. If the dentist wanted to have a known reference point, he would be required to custom fabricate a piece to use in the patience's mouth. This type of device, done as a custom fabrication, is an expensive proposition and can easily cost in excess of 100 dollars. The idea is that the cost of a precision milled ball bearing and a mass produced device would significantly reduce the cost to the dentist, while allowing the dentist to work more efficiently. - In one of the embodiments of the invention, the dental
X-ray reference device 30,FIG. 2 , is comprised of aradiopaque marker 10 having a known dimension that is held into place in a patient's mouth by atooth overlay molding 20. Thetooth overlay molding 20,FIG. 5 , is comprised of anocclusal support member 25, having anupper surface 45,FIG. 6 , and alower surface 55,FIG. 5 , and thereference support member 35, having afront surface 65,FIG. 6 , andback surface 75,FIG. 5 . Thereference support member 35 is configured to support theradiopaque marker 10 having a known dimension. Theocclusal support member 25 of thetooth overlay molding 20 is connected substantially perpendicularly to thereference support member 35. In one of the embodiments of the invention, thetooth overlay molding 20,FIG. 7 , may have areference support member 35 that is curved, so that it will be adapted to follow the dental arch form as shown inFIG. 3 . - This dental
X-ray reference device 30,FIG. 6 , in one embodiment of the invention, may have thetooth overlay molding 20 adapted to secure multipleprecision radiopaque markers FIG. 6 or the radiopaque markers may be of different known dimensions. - In another embodiment, the
dental X-ray reference 30,FIG. 5 , where thelower surface 55 of the planarocclusal support member 25 is configured with a plurality ofgrooves 95. Thesegrooves 95 may run across thelower surface 55 of theocclusal support member 25 thegrooves 95 being substantially perpendicular to thereference support member 35 as shown inFIG. 6 . In another embodiment of the invention, thesegrooves 95,FIG. 8 , may run across thelower surface 55, of theocclusal support member 25, thegrooves 95 being substantially parallel to thereference support member 35, as shown inFIG. 8 . It will also be readily apparent that thelower surface 55 of theocclusal support member 25, may be configured with set or random geometric patterns that would help facilitate holding a temporary adhesive into place. Further thelower surface 55, of theocclusal support member 25 may have grooves that run diagonally or that are not straight but wavy or that form a pattern such as x's, triangles, diamonds or other such shapes. - The
grooves 95,FIG. 8 , or pattern would help facilitate retaining a temporary adhesive in a set location. The temporary adhesive can be any temporary adhesive; examples include but are not limited to polyvinyl siloxane material, acrylic or temporary crown and bridge material. An example of a temporary crown and bridge material is TempSpan® Dual Cure temporary Crown and Bridge material, which is a resin based material, designed for provisional restorations, available from Pentron Clinical Technologies LLC, Wallington Conn. With either thegrooves 95 or a pattern the adhesive could be syringed into place on thelower surface 55 of theocclusal support member 25. In another embodiment of the invention, thelower surface 55 of theocclusal support member 25 is simply a planar surface without grooves or a pattern. In this embodiment the temporary adhesive can be placed on thelower surface 55, of theocclusal support member 25 or it could be used without an adhesive. - The dental
X-ray reference device 30,FIG. 8 , in another embodiment of the invention, the planarreference support member 35 is configured with anorifice 105 adapted to engage a line. This line could be of dental floss or string or twine. Theorifice 105 allows the dentist to tie or pull this line through the orifice. The line can be used so the dentalX-ray reference device 30 can easily be eradicated from a patient's mouth in the event of trouble, for example a choking incident. - In another embodiment of the invention the
radiopaque marker 10,FIG. 6 , may be secured to thereference support member 35 through the use of a moldedlip 110. In one embodiment of the invention, thereference support member 25,FIG. 5 , may have aradiopaque marker orifice 115, which allows theradiopaque marker 10,FIG. 1 , to set further back in thetooth overlay molding 20, so that if a spherical radiopaque marker is used, one side of the sphere can be placed as close as possible to the tooth, as seen inFIG. 2 , without extending beyond therear surface 75, of thereference support member 35. In another embodiment of the invention, theradiopaque marker 10,FIG. 7 , can be secured to thereference support member 35 through the use of retainingarms 120 which are placed about theradiopaque marker 10. In this embodiment the retainingarms 120 leavemultiple viewing windows 125 where theradiopaque marker 10 is visible. When using a sphericalradiopaque marker 10, theviewing window 125 allows the dentist to see how wide theradiopaque marker 10 is; so that the dentist can position the radiopaque marker close enough to the area he wishes to work on so that an accurate reading can be made. - While the
X-ray reference device 30 is envisioned to work withperiapical radiographs 80,FIG. 4 or panoramic images, 100,FIG. 9 , it would also be possible to use theX-ray reference device 30 to produce a tomogram exposure. TheX-ray reference device 30 may also be used to produce periapical radiographs or panoramic images and other non-tomogram exposures. - Place
X-ray reference device 30 on the occlusal surface of thetooth 40,FIG. 2 , with theradiopaque marker 10 placed on the buccal of thetooth 40 surface. A quick set rigid polyvinyl siloxane material, acrylic, or temporary crown and bridge material, may be lightly syringed onto X-ray reference device to help secure X-ray reference device to the tooth surface and ensure that the orientation may be duplicated if a subsequent film is desired. Place thedigital x-ray sensor 50 and or x-ray film to the lingual of thetooth 40 and on top of X-ray reference device and expose the desired radiograph. - Place
X-ray reference device 30 on the occlusal surface of the teeth, or over the crest of the alveolar ridge, with the radiopaque marker centered over the edentulous area. A quick set rigid polyvinyl siloxane material, acrylic, or temporary crown and bridge material, may be placed on the occlusal surface of X-ray reference device to help secure X-ray reference device to the teeth, or align the device on the edentulous ridge, and also to ensure that the orientation may be duplicated if a subsequent film is desired. The polyvinyl siloxane material, acrylic, or temporary crown and bridge material will engage thegrooves 95, on X-ray reference device, 30,FIG. 6 . If polyvinyl siloxane material, acrylic, or temporary crown and bridge material is used X-ray reference device will become a single use patient specific device. When using the acrylic or temporary crown and bridge material take care to seat and remove X-ray reference device while it is setting to prevent X-ray reference device from locking on to the occlusal surface of the teeth. Place thedigital x-ray sensor 50 and or x-ray film to the lingual of thetooth 40 and on top ofX-ray reference device 30 and expose the desired radiograph. - The resulting image will be an image of the tooth or anatomy along with an image of the spherical radiopaque marker. To measure the length of a tooth for example, measure the diameter of the spherical radiopaque marker on the image. Then measure the length of the tooth on the image. To determine the actual length of the tooth solve the simple equation for X below:
-
- Many digital radiography software programs will calibrate a length of an area of anatomy if an object of known length is on the film.
